Downloading, Unpacking and Using !BBC_Draw

This is an Acorn RISC OS software application that converts from BBC BASIC Program Files to Jackson Structure Diagram Acorn Draw Files, and is available for free download.

After having downloaded and unzipped the !BBC_Draw Application, drag the application to a suitable directory on your hard disc. Double click on the !BBC_Draw icon to load it onto the icon bar.

Double click on a BBC BASIC file or drag it to the bar icon to enter its file name into the main 'SetUp' panel slot. Alternatively clicking on the bar icon brings up the main 'SetUp' panel and the BBC BASIC file can be dragged to this panel, or the file name can be typed manually into the slot at the top of this panel.

Select options from the 'SetUp' panel and then click on the 'Run' icon. After a while Draw Files with structure diagrams in them are written to a directory 'BBCDraw' in the same directory as your BBC BASIC. This directory is created automatically, if it doesn't already exist.

In !BBC_Draw Version 1.18, the name of the directory in which the Draw Files are produced can be altered to any name of the users' choice

A text file is also produced, which gives a complete list of identifiers, an abbreviated list of numbered commands and numbered selection and iteration conditions.

Additional Help is available from the bar icon menu, or by using the Acorn facility !Help, present in the 'Apps' directory.

Note that not more than 77 Draw Files will be written to the 'BBCDraw' directory (or chosen directory), and that the files are numbered with two digits, so that this numbering cannot exceed 99.

The drawing numbered '00' is that of the main program and the others are those of the PROC and FN definitions.

Consult !ReadMe within this application for conditions of use.
